论文摘要
AE AQR对象是一类灾难性变量恒星，其中白矮人（WD）的迅速旋转的磁层（WD）初级离心机会在其上积聚到WD上，从而驱散大多数无数的气体。通过此“磁性螺旋桨”驱动积聚流从WD提取角动量，并在光学测定中产生大振幅，上的耀斑。同名AE AQR是该类别对象的唯一确认成员，但最近，Thorstensen（2020）发现了候选AE AE AQR系统：Lamost J024048.51+195226.9。使用调查光度法，我们测量了该系统的精制轨道周期，并确定了一个浅的，未识别的日食，在此过程中，该系统频繁出现类似AQR的弹性发作。对于测试LAMOST J024048.51+195226.9的提议的AE AQR分类仍然需要一项专门的后续研究，但如果得到证实，其耀斑产生区域的日食将提供一种研究磁性螺旋桨现象的新手段。
AE Aqr objects are a class of cataclysmic variable stars in which the rapidly rotating magnetosphere of the white dwarf (WD) primary centrifugally expels most infalling gas before it can accrete onto the WD. The expulsion of the accretion flow via this "magnetic propeller" extracts angular momentum from the WD and produces large-amplitude, aperiodic flares in optical photometry. The eponymous AE Aqr is the only confirmed member of this class of object, but recently, Thorstensen (2020) discovered a candidate AE Aqr system: LAMOST J024048.51+195226.9. Using survey photometry, we measure a refined orbital period for this system and identify a shallow, previously unrecognized eclipse during which the system's frequent AE Aqr-like flaring episodes cease. A dedicated follow-up study is still necessary to test the proposed AE Aqr classification for LAMOST J024048.51+195226.9, but should it be confirmed, the eclipse of its flare-production region will offer a new means of studying the magnetic propeller phenomenon.
